 Projecting Your Computer’s Screen Image from the Projector 
over a LAN (Image Express Utility Lite)
 
Using	Image	 Express	 Utility	Lite	allows	 you	to	send	 the	computer’s	 screen	image	to	the	 projector	 over	a	wired	 or	
wireless	LAN.
This	section	 will	show	 you	an	outline	 about	how	to	connect	 the	projector	 to	a	LAN	 and	to	use	 Image	 Express	 Utility	
Lite.	For	the	operation	of	Image	Express	Utility	Lite,	see	the	help	of	Image	Express	Utility	Lite.
What you can do with Image Express Utility Lite
•	Image	transmission
•	 The	 screen	of	your	 computer	 can	be	sent	 to	the	 projector	 via	a	wired	 or	wireless	 network	without	a	computer	 cable	
(VGA).
•	 By	using	“EASY	 CONNECTION” 	function,	 the	complicated	 network	settings	can	be	simplified	 and	the	computer	
will	automatically	connect	to	the	projector.
•	 The	screen	of	your	computer	can	be	sent	to	up	to	four	projectors	at	the	same	time.
•	Geometric	Correction	 Tool	(GCT)
See	“❹	Projecting	an	Image	from	an	Angle	(Geometric	Correction	 Tool	in	Image	Express	Utility	Lite)”.

 Projecting an Image from an Angle (Geometric Correction Tool 
in Image Express Utility Lite)
 
The	 Geometric	 Correction	Tool	(GCT)	 function	 allows	you	to	correct	 distortion	 of	images	 projected	 even	from	an	
angle. 	
What you can do with GCT
•	 The	GCT	feature	includes	the	following	three	functions
•	4-point	 Correction:	You 	can 	fit 	a 	projected 	image 	within 	the 	border 	of 	the 	screen 	easily 	by 	align 	the 	four 	corners	
of	an	image	to	the	ones	of	the	screen.
•	 Multi-point Correction:	You	 can	correct	 a	distorted	 image	on	the	 corner	 of	a	wall	 or	irregular	 shaped	screen	
by	using	many	separated	screens	to	correct	the	image	as	well	as	4-point	Correction.
•	Parameters Correction:	You	 can	correct	 a	distorted	 image	by	using	 a	combination	 of	transformational	 rules	
prepared	in	advance.
This	section	will	show	an	example	for	use	with	4-point	Correction.
For	information	 about	“Multi-point	 Correction”	and	 “Parameters	 Correction”,	see	the	help	 file	of	Image	 Express	
Utility	Lite. 	(→	page	171)	
•	 Your	correction	data	can	be	stored	in	the	projector	or	your	computer	which	can	be	restored	when	necessary.
•	Geometric	correction	can	be	used	when	connected	to	the	network	(by	wired	or	wireless	LAN)	or	by	video	cable.
Preparation: 	Adjust	the	projector	position	or	the	zoom	so	that	the	projected	image	can	cover	the	whole	screen	area.
1.	 Click	the	 “		”	(Picture)	icon	and	then	the	 “		”	button.
  The “4-point Correction” window will be displayed.
2.	 Click	the	 “Start	Correction” 	button	and	then	“Start	4-point	Correction” 	button.
 A green frame and a mouse pointer (  ) will be displayed.
•	 Four	[	• ] marks will be appeared at four corners of the green frame 
						

							173
8. User Supportware
3.	 Use	the	mouse	to	click	the	[ • ]	mark	of	which	corner	you	wish	to	move.
 The currently selected [ • ] mark will turn red.
(In the above example, Windows screens are omitted for clarification.)
4.	 Drag	the	selected	[ • ]	mark	to	the	point	you	wish	to	correct	and	drop	it.
•	 When	 you	click	 somewhere	 within	the	project	 image	area,	the	nearest	 [	• ] mark will go to the position where 
the mouse cursor is.
5.  Repeat Step 3 and 4 to correct the distortion of the projected image.
6.	 After	completing, 	right-click	the	mouse.
 The green frame and the mouse pointer will disappear from the projected image area. This will complete the cor-
rection.
7.	 Click	the	 “X”	(close)	button	on	the	 “4-point	Correction”	window.
 The “4-point Correction” window will disappear and the 4-point correction will take effect.
8.	 Click	the	 “		”	button	on	the	control	window	to	exit	the	GCT.
TIP:
•	 After	 performing	 the	4-point	 correction,	 you	can	save	 the	4-point	 correction	 data	to	the	 projector	 by	clicking	 “File”	→	“Writing	 to	
the	projector…”	on	the	“4-point	Correction”	window.
•	 See	the	Help	 of	Image	 Express	 Utility	Lite	for	operating	 “4-point	Correction”	 window	and	other	 functions	 than	GCT.	 (→	page

  Projecting  Images  or  Videos  from  the  Projector  over  a  LAN 
(Image Express Utility 2.0)
What you can do with Image Express Utility 2.0
•	 Using	Image	Express	 Utility	2.0	allows	 you	to	send	 the	screens	 of	your	 computers	 to	the	 projector	 via	wired/wire-
less	LAN.
	 The	 difference	 from	Image	 Express	 Utility	Lite	is	that	 projected	 images	can	be	sent	 from	 a	computer	 to	not	 only	
one	projector	but	also	to	two	or	more	projectors	at	the	same	time.
	 When	 “Meeting	Mode” 	is	used,	projected	images	can	be	sent	and	received	between	two	or	more	computers.
•	 High-speed, 	high-quality	image	transmissions	based	on	NEC’s	original	compression	algorithm
	 NEC’s	original	compression	 algorithm	allows	high-quality	 images	to	be	 sent	 over	 the	network	 at	high	 speed,	 from	
your	computer	to	the	projector.
•	 Simultaneous	projection	by	multiple	projectors
	 Images	 can	be	sent	 from	 a	computer	 to	not	 only	 one	projector	 but	also	 to	two	 or	more	 projectors	 at	the	 same	
time.
•	 “Easy	Connection” 	function	for	connecting	wireless	LAN
	 By	using	“Easy	Connection” 	function*1,	the	complicated	setting	of	wireless	LAN	can	be	simplified.
*1	 This	function	 can	be	used	 when	 Windows	 XP	is	used	 as	the	 OS	 and	 when	 you	have	 a	“Computer	 Adminis-
trator”	privilege. 	If	 the	 OS	 is	Windows	 7/Windows	 Vista,	input	of	logon	 password	 as	“Administrator” 	may	 be	
prompted.

•	 Projected	images	can	be	transferred	and	saved	to	computers.
	 When	“Meeting	Mode”	is	 used,	 projected	 images	can	be	sent	 to	the	 computers	 of	all	 the	 participants	 (attendants)	
of	a	“Meeting”. 	The	received	images	can	be	saved	to	your	computer	with	a	memo	(text	data)	attached.
